Speaking to the lads at Stonelake the other day about a rear diff for mine they said Ashcroft every time same as with the Outputshaft which I have fitted and they have done a few now with no failures.

there are several threads on here about this issue and no one has reported an Ashcroft failure yet, for an overlander the Ashcroft kit should be considered an insurance policy against the inevitable standard shafts ultimate demise DEFENDER 90 TDCI XS,
I hope everyone is well and your land rovers make you happy |

The thing that makes me uneasy about the Ashcroft mod, is it’s effectively a controlled gearbox oil leak- two problems with that, could it leak enough to affect the fluid level? Second could contaminates from the output shaft, e.g. metal particles make their way back into the gearbox?
Perhaps I’ve misunderstood and certainly I’ve not heard of problems with the Ashcroft mod, but their concept makes me uneasy. What’s stopping someone modifying the shaft housing to include a grease nipple? 2014 Keswick Utility 2.2 |

/\ already done.
I think SeriesIan (think that's him on here  )
seemed like an excellent solution? |

yes several have done a home made grease nipple mod and as Caterham states Ian Series one has done it DEFENDER 90 TDCI XS,

I suppose that the connection is inside a housing that these guys have to unmount before they are able to change the shaft.
The grease nipple is somehow uncomfy to reach, isn't it? Although the grease nipple is the best solution. In both my Citroën 2CV was the same connection with a grease nipple. My Land Rover is now in garage for harvest machines. These guys were laughing at me when they saw the connection without the nipple saying: "in each and every harvest machine these connections have a grease nipple." These experienced guys all knew that too much wear occurs without renewing the grease. But without grease ?? That's awful. Well, Land Rover, shame on that ... |

Here you go.
 Click image to enlarge I put a grease nipple in mine a few years ago, drilled and tapped the outer case to accept a gear box level bung, Which is a good size to get the grease gun through. It gets a few pumps when I do the UJs, not had any issues so far? I do a fair amount of towing, and covered well over 40,000 miles. I work on a lot of plant equipment, and as said above anything that’s got a pivot, bearing, splined joint etc needs to be greased, not sure what JLR were thinking at the time?? 
I’ve replaced a few of these now, some wear really badly, others hardly have a mark on them? Anyway, Cheap experimental fix and it seems to have worked for me. 80" 80" 86" 88" 90"

Nice one. Now you posted the pic I think I remember seeing it before. So, this is a transfer box off job? Did you do it originally because of a failure, or as a precaution? 2014 Keswick Utility 2.2

Ashcroft modifies the original Land Rover parts. After installing the lubricated parts the mod cannot be worse than the original parts 
Metal particles are also inside the gearbox. An oil change may help ... The grease nipple is not the problem - but what about the old grease inside the housing. The housing has to be removed in order to sort the old grease. @Ian Series: The nipple is not the problem. The guys at the garage will install it within a few minutes. But what about the accessibility and the maintenance? A picture after installation would be helpful. But its hidden inside the housing and one cannot see what happens while shooting with the grease gun ... That's not too clever, is it? Last edited by Julie on 10th May 2018 7:34pm.

Julie- there is no grease nipple in the original install. it appears how well greased the output shaft is when it was originally installed at build has some bearing on how long it all lasts before failing. 2014 Keswick Utility 2.2

Utility Truck, the nipple is a DIY mod - I know. Although lubrication is essentiel.
It appears that there's no grease in a connection after it failed. Land Rover have the dealers lubricate the connection while installing the replacement. From what I read in the web the connection may fail if lubricated or not ... 
Lubricated or not - after its failure you're going to find only the rust and no grease. 
And what happens inside the housing? Nobody knows ... With or without nipple - we have to remove the housing and check if the grease gun was successful or not - i.e. a EUR 1000 / GBP 800 maintenance every 3 years  |

I would go for the Ashcroft solution if you want zero maintenance. I’m sure it is well thought out product, t the end of the day they’re Land Rover gearbox specialist so I’m sure they’ve seen a lot of failures to come up with a solution that works. Their after sales service is second to none, the advice is always free and I’ve had Dave contact me after hours because “I didn’t want to leave you waiting” cant ask for more than that in my eyes

I did mine due to a clutch rattle, my shaft was still good at 85k with very little wear, It was more of a precaution, as I had already done one at work which had failed. Personally I find them a faff to do with the box in situ, they are so much easier to do on the bench! I drop the box and transfer box in one, I tend to replace the clutch while I’m there.
Julie, There isn’t much to see other than a oil plug at the bottom of the adaptor shaft casing! Undo the bung, turn the prop until you can see the grease nipple through the hole, I use a fixed head grease gun which is easier to get on the nipple, rather than a flexible one. I can’t see excess grease being an issue? It may also look like the grease only gets around one side with one nipple, This is not the case, it finds its way around the whole circumference, 80" 80" 86" 88" 90"

The grease is going to find its way. After some miles the gear box becomes so warm what makes the grease very fluid.
Maintenance with a grease gun: Under normal conditions one has to check if the old grease came out / stop if the new grease comes. Also keep the outside dry and clean in order to prevent dirt creeping into the connection. Surprisingly, the MT82 shaft is not the first "dry shaft" in the history of the defender. Land Rover made the same mistake with the LT77 / Defender TDI 200: And Land Rover found out how to protect the shaft from wearing. They developed parts with holes allowing the gearbox oil to sink in ... Now Ashcroft follows the same strategy ! |
